Unrelated, but I had something relatively similar once with my Inspiron 7520 laptop. In theory, that machine only supports 8GB of RAM, but technically I could put 16 into it and worked fine. Later I upgraded to a different machine and put this laptop aside, but sometimes I set it up if I go to friends place and need a PC to do some light multiplayer lan parties or such.
For a while, the laptop has a strange locking up issue when I booted 64 bit OSs. Or I don’t know, after my testings, it seemed that booting a 64 bit OS would crash my machine sooner or later. Maybe even right after boot, maybe after when I logged in or used it for some time. Booting into Memtest also locked up eventually the laptop (but running the 32 bit version of Memtest didn’t). Pulling out either memory stick (2x8GB) solved the issue, it worked with both sticks on both slots, if I used only one. The two sticks together on the other hand made my machine crash after boot, no matter which stick went to which slot.
Difference is that every OS did this, not just Debian, though Windows seemed to keep up longer in this case, but it also crashed on me.
Now I don’t have this problem. It just… disappeared after not using the laptop for a while again.
So… if it’s not software issue, maybe try to reseat your RAM sticks. Or use some compressed air to clean up the slots, maybe check the contacts of the sticks and clean them with some isopropyl and a soft brush.
It also can be storage issue, if your Windows install works fine on a different drive. Once I had an Ubuntu installed to the same laptop I mentioned and its HDD was failing hard, but the system kept up for a while, just had some really weird issues popping up here and there. But then eventually failed completely. Amongst the weird happenings, random freezes were also a thing with my bad HDD.




That’s what it is. I remember actually sideloading apps to my BlackBerry 10 devices (Z10 and Z30) (though it really wasn’t that long ago not to remember it…) using a PC with a Chrome based browser (though it worked on Firefox too with some minor fiddling) to push and install .bar files to the phone. That is what sideloading to me.
Now this term changed, so everything you install from a different source than the built-in appstore is called sideloading, which is ridiculous IMO.
